System and Methods for Diagnosis and Treatment of Discogenic Lower Back Pain

Methods and devices to treat discogenic lumbar back pain are disclosed. Electrodes are implanted within the anterior epidural space of the patient. A pulse generator that is connected to the electrodes delivers electrical impulses to sympathetic nerves located within the posterior longitudinal ligament (PLL) of the lumbar spine and outer posterior annulus fibrosus of the intervertebral disc. In alternate embodiments, energy directed to nerves in the PLL may be from light or mechanical vibrations, or the nerves may be cooled. The electrodes may also be used diagnostically to correlate spontaneous nerve activity with spinal movement, fluctuations in autonomic tone and the patient's experience of pain. The electrodes may also be used to generate diagnostic evoked potentials. The diagnostic data are used to devise parameters for the therapeutic nerve stimulation. Automatic analysis of the data may be incorporated into a closed-loop system that performs the nerve stimulation automatically.

Quick crank adjustable height table

A table or desk assembly (20) includes a base having a pair of legs (24), a worksurface (22) supported by and between the pair of legs, and a rapid, counterbalanced height adjustment mechanism interposed between the legs and the worksurface for providing adjustment in the elevation of the worksurface. The height adjustment mechanism includes a pair of high lead rotatable threaded rods (32) engaged with a mating stationary threaded member (33) associated with each leg. A handle (36) is engageable with one of the threaded rods for imparting rotation to the threaded rod, and a synchronizing arrangement, such as a sprocket (38) and chain system (40), is interconnected with the other of the threaded rods for rotating the threaded rods together. A lift assist or counterbalancing mechanism applies an upward bias, such as to the worksurface, to counteract the weight of the worksurface and any loads supported by the worksurface. The counterbalancing mechanism may be in the form of a cylinder assembly (54) having a biased retractable and extendible member, which is interconnected with each of the threaded rods via a cable (66) and pulley (68) arrangement. Alternatively, the lift assist or counterbalancing mechanism may be in the form of constant force spring arrangements (76), each of which has an extendible and retractable member. A retainer arrangement (90) is interposed between the crank or handle member (36) and the worksurface, for preventing inadvertent rotation of the threaded rod and thereby maintaining the elevation of the worksurface.

Product and package fastening apparatus and method

An apparatus for fastening a product to its package for shipment and display. The apparatus includes a key having a base, an inner pad and outer ring portions. The base includes two bridges supporting two pairs of living hinges, each of the pairs being connected to an outer ring portion. The outer ring portions are enabled to pivot between a position generally aligned with the inner pad and a position generally perpendicular to the inner pad so as to act as a handle to rotate the key. The inner pad supports a post and a pair of protrusions. Between the inner pad and the outer ring portions are openings for receiving a strip of stiff paper. After the key is inserted through the package and into the product, the key is rotated to cause an abutment of the protrusions with the product to fasten the product and package together. The strip is then inserted to prevent inadvertent rotation of the key. After purchase, a consumer may easily and quickly remove the strip, rotate the key and remove it from the product and the package to enable the product to be separated from the package, and the package and the key to be disposed. Multiple keys are used with multiple strips incorporated in a stiff paper panel. Each strip takes the form of a hole in the panel flanked by two strip tabs that connect to the key inserted through the hole of the strip. A reinforcing support may be placed between the panel and the package.

Anti-Decoupling device for a spin coupling

An anti-decoupling device for use in preventing undesired rotation of a spin coupling of, for example, a two-part electrical connector, is disclosed. The anti-decoupling device can form part of a new connector, or can be used to retrofit existing connectors without having to modify the connector. In some embodiments, the anti-decoupling device comprises a base and two prongs that extend in a generally axial direction relative to the base. Blades that depend from the prongs extend into channels within the knurled side-edge of the spin coupling. The blades prevent inadvertent rotation of the spin coupling.

Ratcheting strap with take-up reel and hook storage

A ratcheting strap device has an elongate body with a reel axis towards a first end and a ratcheting mechanism towards a second end opposite there-from. The ratcheting mechanism is affixed to the body, and has a spool axis and a ratchet spool rotatable relative to the body there-about. A first strap/hook member has a first length of strap affixed to a first one of the ratcheting mechanism and the body at a first proximal end, and has a first hook affixed to a first distal end there-of. A take-up reel is affixed to the body and rotational relative thereto about the reel axis. A second strap hook member has a second length of strap having a second proximal end connectable to the take-up reel, has a take-up strap portion adjacent to the second proximal end and windable around the take up reel, and has a second hook affixed to a second distal end there-of. The second length of strap has a midsection between its second proximal and distal ends, passing through and engageable by the ratchet spool such that rotation of the spool causes the midsection to be wound there-around. A first receiving pocket is disposed on one of the body and the ratcheting mechanism for receiving the first hook during a storage condition in a manner which leaves no slack in the first length of strap, and a second receiving pocket is disposed on one of the body and the ratcheting mechanism for receiving the second hook during the storage condition in a manner which allows take-up of any slack in the second length of strap by the take-up reel.
